  • Purpose: Screening serologic tests are important tools for the diagnosis of celiac disease (CD). Immunoglobulin (Ig)G anti-deamidated gliadin peptide (anti-DGP) is a relatively new autoantibody thought to have good diagnostic accuracy, comparable to that of anti-tissue transglutaminase (anti-tTG) antibody. Methods: Pediatric patients (n=86) with a clinical suspicion of CD were included. Duodenal biopsy, anti-tTG, and IgG anti-DGP antibody tests were performed. The patients were divided into CD and control groups based on the pathological evaluation of duodenal biopsies. The diagnostic accuracy of serological tests was determined. Results: IgA anti-tTG and IgG anti-DGP antibodies were positive in 86.3% and 95.4% of patients, respectively. The sensitivity, specificity, and diagnostic accuracy of the IgA anti-tTG test were 86.3%, 50.0%, and 68.6%, respectively, and those of the IgG anti-DGP test were 95.4%, 85.7%, and 90.7%, respectively. The area under the receiver operating characteristic (ROC) curve was 0.84 (95% confidence interval [CI], 0.74-0.91) for IgA anti-tTG test and 0.93 (95% CI, 0.86-0.97) for IgG anti-DGP test. The comparison of IgA anti-tTG and IgG anti-DGP ROC curves showed a higher sensitivity and specificity of the IgG anti-DGP test. Conclusion: IgG anti-DGP is a reliable serological test for CD diagnosis in children. High tTG and DGP titers in the serum are suggestive of severe duodenal atrophy. The combined use of IgA anti-tTG and IgG anti-DGP tests for the initial screening of CD can improve diagnostic sensitivity.

  • The efficacies of a supraglottic airway device (SGAD) and an endotracheal tube (ETT) in cats under general anesthesia with volume-controlled ventilation (VCV) were compared. Thirty healthy cats were randomly allocated for airway control using either an SGAD or an ETT. Five tidal volumes (6, 8, 10, 12, and 14 mL/kg) were randomly tested, and respiratory rates were adjusted to achieve a minute ventilation of 100 mL/kg/min. The dose of propofol necessary to insert the SGAD or ETT, the static respiratory pressure, leakage during VCV, and end tidal CO2 (ETCO2) were recorded. Dosages of propofol and static respiratory measurements for the SGAD and ETT groups were compared using a t-test. The distribution of leakages and hypercapnia (ETCO2 > 45 mmHg) were compared using Fisher's exact test. A significance level of p < 0.05 was established. No significant difference in dose of propofol was observed between the SGAD and ETT groups (7.1 ± 1.0, 7.3 ± 1.7 mg/kg; p = 0.55). Static resistance pressure of the SGAD (22.0 ± 8.1 cmH2O/L/sec) was significantly lower than that of the ETT (36.6 ± 12.9 cmH2O/L/sec; p < 0.01). Of the 75 trials, leakage was more frequent when using an SGAD (8 events) than when using an ETT (1 event; p = 0.03). Hypercapnia occurred more frequently with SGAD (18 events) than with ETT (3 events; p < 0.01). Although intubation with an ETT is the gold standard in small animal anesthesia, the use of an SGAD can reduce airway resistance and the work of breathing. Nonetheless, SGAD had more dead space and the tidal volume for VCV needs adjustment.

  • Purpose: This study was performed to explore and describe the overall clinical practice adaptation experiences among nursing students during the COVID-19 pandemic. Methods: This qualitative study applied the grounded theory method by Corbin and Strauss. Data were collected from May to August 2021 through individual in-depth interviews with 14 nursing students from three universities in B metropolitan city. Results: From open coding, 20 sub-categories and 10 categories were identified. Analysis revealed that the core category was the process of "keeping the place of learning while adhering to the restrictions of the era of pandemic" and that it consisted of four phases: confusion, withdrawal, adjustment, and growth. Through this process, participants utilized various action/interactional strategies such as "shifting to positive thinking," "building a shield to protect oneself," and "focusing on learning." The consequences of these strategies were "adapting to the reality of the infectious disease situation" and "strengthening a foothold to grow as a future nurse." Conclusion: An in-depth understanding of nursing students' experiences of adapting to clinical practice during the COVID-19 pandemic will guide nursing educators to promote effective teaching strategies to better support nursing students in a time of infectious disease crisis.

  • A 10-year-old, spayed female miniature schnauzer was referred to the Veterinary Medical Teaching Hospital of Chungnam National University due to evaluation of sudden polyuria (PU) and, polydipsia (PD) (540 mL/kg/day) with severe anemia and weight loss. Blood examination results were normal except for severe anemia (hematocrit, [HCT]: 11.8%). Urinalysis revealed a urine specific gravity (USG) of 1.003, whereas urine sediment was not specific. Urine osmolality was 90 mOsm (reference range: 800~2500 mOsm), and plasma osmolality was 303 mOsm. No specific lesions were found using diagnostic imaging including radiography, ultrasonography and magnetic resonance imaging (MRI). The serum cortisol level was normal in cosyntropin stimulation test. Plasma arginine vasopressin (AVP) concentration was <0.4 pg/mL (reference range: 3.49~5.45 pg/mL). Blood transfusion was initiated in addition to an oral prescription of desmopressin acetate (DDAVP, 0.1 mg/head) thrice a day for one week. The patient was rechecked for clinical signs, urine osmolality, and USG; the clinical signs of PU/PD were resolved, urine osmolality increased to 1106 mOsm, and, USG increased to 1.021. Considering the improved clinical signs, and increased urine osmolality, and USG after DDAVP treatment, the dog was diagnosed with central diabetes insipidus. USG and urine osmolality increased to >1.030 and 2200 mOsm, respectively. Anemia also gradually improved and HCT increased to >37%. DDAVP was tapered to 0.1 mg/head twice a day and all clinical signs in the patient have completely resolved.

  • The purpose of this study was to identify the influencing factors on the intention of career choice toward psychiatric nurses among nursing students. The participants were 261 senior nursing students from five schools in D and W metropolitan cities. Data were collected from August 1 to 20, 2019, and analyzed by descriptive statistics, t-test, Pearson Correlation Coefficient, and multiple regression using SPSS 26.0 program. In the multiple regression analysis, age (𝛽=.13, p=.048), satisfaction of mental health nursing practicum (𝛽=.16, p=.035) were significant factors on intention of career choice toward mental nurses with 10.3% of total explanatory power. Therefore, it is necessary to improve the practice satisfaction of nursing students by improving the practice environment and clinical nursing instructors' teaching competence. In addition, an further study was proposed that can identify various variables that affect the career choice of mental health nurses by expanding the subjects.

  • Background: The relationships between the postpartum subacute ruminal acidosis (SARA) occurrence and predicted bacterial functions during the periparturient period are still not clear in Holstein cows. Objectives: The present study was performed to investigate the alterations of rumen fermentation, bacterial community structure, and predicted bacterial functional pathways in Holstein cows. Methods: Holstein cows were divided into the SARA (n = 6) or non-SARA (n = 4) groups, depending on whether they developed SARA during the first 2 weeks after parturition. Reticulo-ruminal pH was measured continuously during the study period. Reticulo-ruminal fluid samples were collected 3 weeks prepartum, and 2 and 6 weeks postpartum, and blood samples were collected 3 weeks before, 0, 2, 4 and 6 weeks postpartum. Results: The postpartum decline in 7-day mean reticulo-ruminal pH was more severe and longer-lasting in the SARA group compared with the non-SARA group. Changes in predicted functional pathways were identified in the SARA group. A significant upregulation of pathway "PWY-6383" associated with Mycobacteriaceae species was identified at 3 weeks after parturition in the SARA group. Significantly identified pathways involved in denitrification (DENITRIFICATION-PWY and PWY-7084), detoxification of reactive oxygen and nitrogen species (PWY1G-0), and starch degradation (PWY-622) in the SARA group were downregulated. Conclusions: The postpartum SARA occurrence is likely related to the predicted functions of rumen bacterial community rather than the alterations of rumen fermentation or fluid bacterial community structure. Therefore, our result suggests the underlying mechanisms, namely functional adaptation of bacterial community, causing postpartum SARA in Holstein cows during the periparturient period.

  • Sports activities, including playing tennis, are popular with many people. As this industry has become more professionalized, investors and those involved in sports are sure to pay attention to any tool that improves athletes' performance Tennis requires perfect coordination between hands, eyes, and the whole body. Consequently, to perform long-term sports, athletes must have enough muscle strength, flexibility, and endurance. Tennis rackets with new frames were manufactured because tennis players' performance depends on their rackets. These rackets are distinguished by their lighter weight. Composite rackets are available in many types, most of which are made from the latest composite materials. During physical exercise with a tennis racket, nanocomposite materials have a significant effect on reducing injuries. Materials as strong as graphite and thermoplastic can be used to produce these composites that include both fiber and filament. Polyamide is a thermoplastic typically used in composites as a matrix. In today's manufacturing process, materials are made more flexible, structurally more vital, and lighter. This paper discusses the production, testing, and structural analysis of a new polyamide/Multi-walled carbon nanotube nanocomposite. This polyamide can be a suitable substitute for other composite materials in the tennis racket frame. By compression polymerization, polyamide was synthesized. The functionalization of Multi-walled carbon nanotube (MWCNT) was achieved using sulfuric acid and nitric acid, followed by ultrasonic preparation of nanocomposite materials with weight percentages of 5, 10, and 15. Fourier transform infrared (FTIR) and Nuclear magnetic resonance (NMR) confirmed a synthesized nanocomposite structure. Nanocomposites were tested for thermal resistance using the simultaneous thermal analysis (DTA-TG) method. scanning electron microscopy (SEM) analysis was used to determine pores' size, structure, and surface area. An X-ray diffraction analysis (XRD) analysis was used to determine their amorphous nature.

  • PURPOSE: The functional limitations in stroke survivors promote sedentary lifestyles and quality of life inadequacies, but there is increasing evidence that this could be minimized by physical exercise. Therefore, this study examined the effects of physical exercise on the quality of life (QoL) and functional capacity (ability to stand up from a sitting position) among stroke survivors drafted from two tertiary hospitals in Osogbo, Nigeria. METHODS: A purposive sampling technique was used to select 21 registered right or left outpatient hemiplegic stroke survivors in a pre- and post-test experimental research design. The research questions were presented using descriptive statistics of frequency, percentage, mean and standard deviation, while an Analysis of Variance (ANOVA) was used to test the study hypothesis at the .05 alpha level for significance. RESULTS: Compared to the baseline (week 0), there were significant increases in the general quality of life, healthy well-being, physical exercise, pain perception, and environmental domains of QOL among the survivors in week four. Moreover, a significant increase was observed in these indices in week eight, compared to week four, except for the pain perception domain. Compared to the baseline, there was a significant decrease in the time it took the stroke survivors to stand up from a sitting position in week four. A significant decrease was observed in this index in week eight compared to week four. CONCLUSION: Marked corridor 20 meters brief walking exercise for eight weeks significantly improved the quality of life and ability to stand up from a sitting position in stroke survivors in Osogbo, Nigeria.

  • A 6-year-old intact male Cane Corso dog weighing 40 kg with a 2-month history of dysuria, dyschezia, anorexia, intermittent panting, and penile discharge presented to the Veterinary Medical Teaching Hospital of Jeju National University. Examination revealed a giant paraprostatic cyst (PPC) that occupied a large part of the abdomen and caused displacement of organs. Radiography, ultrasound, and computed tomography (CT) scans confirmed that the PPC had spread to the pelvic regions. Subtotal resection was performed, leaving two sites with PPC remnants. One site was the prostate gland, which communicated with, and adhered to, the PPC; the other site was the pelvic region, where the PPC had spread. The reason for leaving two remnants was that an anatomical approach for complete resection was difficult, and to avoid complications associated with prostatic urethra damage. Routine omentalization and castration were performed. Partial cystectomy was performed because of the presence of a diverticulum-like lesion in the ventral part of the urinary bladder. The patient's clinical symptoms, including dysuria, completely resolved, and voluntary urination was possible 1 day post-operatively. Histopathological examination revealed osseous metaplasia of the PPC. The patient was well-managed and had no post-operative complications or recurrence until day 180 of follow-up.

  • A 3-year-old, 20.6 kg, neutered male German Shepherd dog was referred to Kyungpook National University Veterinary Medicine Teaching Hospital. Clinical examination revealed chronic diarrhea for 6 weeks and a non-tender, distended abdomen without lethargy, anorexia, and vomiting. Diarrhea was watery and had a waxing and waning course despite symptomatic treatment. A complete blood count identified mild leukocytosis and mild anemia. Serum biochemistry analysis showed elevated alanine aminotransferase and aspartate aminotransferase levels, and mild hypoalbuminemia. Abdominal ultrasound examination revealed mixed echogenicity with absent blood flow at the caudate process of the caudate liver lobe and a small amount of ascites. Computed tomography revealed torsion of the caudate process of the caudate liver lobe and spleen and gas dilatation of the intestine. After establishing a diagnosis of organ torsion on imaging, we deemed the condition an emergency and immediately performed surgery. Given that laparotomy confirmed organ torsion, liver lobectomy, total splenectomy, and prophylactic gastropexy were conducted. The patient was discharged 11 days after surgery without complications. In general, liver lobe torsion and splenic torsion are uncommon in dogs and present with nonspecific clinical signs, such as abdominal pain, lethargy, anorexia, and vomiting. In the current case, torsion of the caudate liver lobe and spleen occurred without other clinical signs except for a distended abdomen. Moreover, no reports in dogs have demonstrated the simultaneous occurrence of both diseases.
